Abstract (en)
[origin: EP2562354A2] An airfoil (18) includes an airfoil wall (28) having an exterior airfoil surface (30) and an interior surface (32). The interior surface (32) provides an airfoil cavity (34). A baffle (24) is arranged in the airfoil cavity (34) and provides a baffle wall (44) having first and second portions (48,50) spaced from one another on first and second sides. A tube (66) interconnects the first and second portions (48,50) and is configured to convey fluid through the tube (66) between the first and second sides. The airfoil (18) is cooled by supplying cooling fluid to the baffle (24). The cooling fluid is passed through baffle cooling holes (62) to a gap (76) between the baffle (24) and airfoil (18) to cool the interior surface (32) of the airfoil (18). A portion of cooling fluid is conveyed from one gap location (76) to another gap (76) through the tube (66). Another portion of the cooling fluid is passed through film cooling holes (43) in the airfoil (18).
